Check Digit Verification of cas no
The CAS Registry Mumber 227305-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,3,0 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 227305-69:
(8*2)+(7*2)+(6*7)+(5*3)+(4*0)+(3*5)+(2*6)+(1*9)=123
123 % 10 = 3
So 227305-69-3 is a valid CAS Registry Number.

(Chemical Equation Presented) Step by step: Highly selective cross dehydrogenase arylation of acetanilides was developed to construct biaryls under mild condition. With this method, different aryl C-H bonds were activated in sequential reactions to construct functionalized carbazoles (see scheme), which are present as key structural units in various biological molecules and organic optical materials.
